    Re: Deep drilling holes at 6000 rpm.

    I ran with door open and blasting coolant just to the left of the bit. My coolant flow is much faster than the bit surface velocity. I ran 10 holes and 10 holes again. I also raised the step over so...

    Re: Deep drilling holes at 6000 rpm.

    Carbide not long as why it is used as a spot drill. I moved the coolant jets so they are not jetting directly towards the hole and that did not work. I am currently looking at bits with a loupe and...

    Change G0 acceleration

    I have the GX1000 OSP with the OSP200M controller. Is there a way to change the acceleration of the rapid G00 motions. Even at 30%, the machine acceleration is large.

    Re: Breaking Small Drill Bits in 7075

    Both of the above look accurate. You can try baby oil and a brush. It is not bad for your skin and does the job when you do not have flood coolant. If you manually use air, remember to direct the...

    Milling Female threads.

    I need to make M25-1 H6 female threads using a thread mill. I looked on a chart and it specifies that the Major diameter be 25.314. Do I make the bore 1mm under or use the minor diameter of 24.15 or...
  11. Re: How does one write g-code that is modal.

    I have written CALL O123 in the past for drilling. I would like to keep it clean and universal such as the following:

    Re: Edge finder for small diameter.

    I think the picture is loaded. It is sitting in a drawer. I bored the holder like a vertical lathe and the router is still about 0.01" off.

    I just found a solution. Using a normal cat40 spinning...

    Edge finder for small diameter.

    I made a router tool that fits in a cat40 holder for my milling center. It is driven by a separate VFD and uses the wash pump for cooling. Note the cat40 spindle does not spin. It is something I made...

    Adding a 4th axis.

    I have a GX 1000 OSP milling center with Okuma controls. I want to add a 4th axis. Are any of these systems interchangeable?
  16. Re: My GX1000 OSP having trouble using Renishaw.

    I now figured it out. My book listed a tool offset as a work coordinate. I can now automatically find the z=0 position.
  17. Re: My GX1000 OSP having trouble using Renishaw.

    deadlykitten, Thank you very much. I now have the touch probe working again. What macro do you use to get the Renishaw probe to find a z-axis point on a part? I have tried CALL OO10 PMOD = 3 PEI...
  18. Re: My GX1000 OSP having trouble using Renishaw.

    I found these variables VSTOD . They appear to give 5 values for x, y, and z.
    I will work on this later.
    Another problem has appeared in the touch sensor system.

    I enter CALL OO30 VFST= #81H. I...

    Re: Coolant or air with steel.

    Hi,
    I saw a similar thread and someone stated that water can cause thermal shock. However, most people use liquid coolant with aluminum and thermal shock is never an issue.
